1. The raw_data folder includes all the experimental data (Fig.1-3) and calculation codes (Fig. 4) shown in the main text. The SM_figs folder include all the data shown in the supplementary materials.
2. All the 2D current maps are stored in txt files (each txt file include a single 2D current map).
3. Each spectrum in the gate dependent tunneling current and dI/dV spectra are stored as a single dat file.
